Title: Frequency-variable light source and optical fiber inspection device
Inventor: ARIHARA MAMORU
IPC: H04B10/548
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To provide an inspection device wherein accuracy of measurement distance and resolution are improved with the ruse of a frequency-variable light source by outputting control signal from a control circuit so that detection output of straight line sweeping error of light frequency of a light source becomes zero. SOLUTION: When inclination of variation of light frequency of the output of a light source 5 is constant (straight-line-swept), the frequency of the signal outputted from a photodetector 17 is constant. The signal outputted from the photodetector 17 is, with a phase comparator 19, compared with known frequency signal outputted from art oscillator 18 for frequency or phase. At this time, when the inclination of variation of modulation frequency does not constant, the error signal is outputted from the phase comparator 19. A lump wave generator 3 is provided with an integrator containing a calculation amplifier 28 and a register 25, and integrates the output current of a control circuit 20.  Thus the output of the control circuit 20 is added to the integrator, so that the output of the phase comparator 19 is so closed-loop- controlled as to be zero, and the light frequency of the light source 5 is straight-line- swept with high accuracy.

Title: Optical system for illumination
Inventor: NAGATA SHINICHI
IPC: G02B19/00
Filed: 1986-01-31
Abstract: PURPOSE:To illuminate brightly a wide range with uniform luminance distribution and short optical path length by constituting an optical system so that the incident height of light beams emitted from a light source and incident upon the optical system is practically proportional to the tangent of an outgoing angle. CONSTITUTION:The incident height (h) of light beams emitted from the light source L and made incident upon the optical system is made proportional to the tangent, tantheta, of the outgoing angle theta. When it is defined that the height, i.e. irradiation height, of light beams radiated from the light source L, made incident with the incident height (h) and reached to a surface S to be irradiated is H, a position P forming a real image of the light source L is P and a distance between the point P and the irradiated surface S is (b), the outgoing angle or the height H are changed in accordance with the increase of the incident height (h), but the length (b) is regarded as a constant value. When the radius of an area on the irradiated surface S irradiated by the light made incident upon a range with a radius A0 around the optical axis at an incident iris A is S0, the value A0 is proportional to the value S0. Consequently, the distribution of the intensity of illumination on the surfaces S to be irradiated becomes the same as that of the incident iris A0 over the whole surface and the distribution of the intensity of illumination can be made uniform.

Title: Heat transfer device
Inventor: MATSUZAKI ATSUSHI
IPC: F28D15/02
Filed: 1981-02-18
Abstract: PURPOSE:To achieve a high degree of heat transfer characteristics by a method wherein heat is transferred by utilizing phase changes of a working medium in a container, in a heat transfer device having a heat-receiving part located above a heat-radiating part. CONSTITUTION:When the heat-receiving part 4A consisting of an upper part of the container 4 is heated and the heat-radiating part 4B consisting of a lower part of the container 4 is cooled, the working medium 5 in the container 4 is solidified by releasing heat at the heat-radiating part 5. Since the solidified material 6 has a lower density than that of the liquid state, it is moved upward in the container 4 due to the difference in density to reach the heat-receiving part 4A. The part 4A is supplied with heat by heating from outside, so that the solidified working medium (the solidified material) 6 is melted to be a liquid again. Accordingly, the working medium 5 is subjected to solidification and melting repeatedly in the container 4, and the heat of phase change is transferred between the inside and the outside of the container 4, achieving a transfer of heat.

Title: Wire system buffering method
Inventor: WATANABE KOUICHI
IPC: F16L55/00
Filed: 1978-02-28
Abstract: PURPOSE: To prevent the secondary breakdown of a pipe due to the pipe whip which is generated when the piping system of a generator plant is broken, by arranging several pieces of wires around the piping system.  
     CONSTITUTION: When a pipe 1 is broken midway on the piping system, pipe whip is generated. The pipe having been swung around contacts with the wire 2 fixed on a construction 6 and pulls the wire 2 to the yielding point and contacts with the wire 3, consuming impact energy. Through the repetition of the above actions, impact energy is consumed till the arrival at the wire 4, and pipe whip is ceased by the last wire 5. Thus, owing to the usage of several pieces of wires, the load applied to a construction or structure due to impact can be reduced, and the secondary breakdown of the pipe can be prevented.

Title: Numerically controlled machine tool equipped with absolute position discriminating function
Inventor: TSUTSUI KATSUNORI
IPC: G05D3/12
Filed: 1989-01-31
Abstract: PURPOSE:To discriminate the absolute position of a machine mobile part at the time of inputting a power source without using an expensive absolute position detector with high resolution by providing an initial moving means and a machine coordinates setting means. CONSTITUTION:The absolute position of a machine mobile part 3 is always stored and reserved with rough resolution by a rough position detector 9 to an absolute position detecting means 21. When the power source is inputted, the machine mobile part 3 is moved in a slight distance by an initial moving means 15, and when a latch signal 22a is generated, a machine coordinates setting means 16 settingly stores a value 21a in the absolute position at such a time to a machine coordinates detecting means 12. The absolute position reserved in the absolute position detecting means 21 and the position of the machine mobile part 3 are accurately matched. Thus, by using the inexpensive absolute position detector having only the rough resolution, the absolute position can be accurately discriminated and controlled in a short time at the time of inputted the power source.
